Definitions

  • oxygen flame cutting machines are used as separating devices for the subdivision of almost endless cast, horizontally emerging strands from continuous steel casting plants for billets, blocks and small slabs.
  • the pendulum-like or straight over the strand cutting torch is held and moved on a machine, the housing of which is round or angular, partially or completely double-walled from sheet metal, possibly welded together with light rolled profiles and through which cooling water flows.
  • Simple machine housings are also used, the heat protection of which is provided by independent heat protection plates attached to the housing, predominantly through which cooling water flows.
  • the separating device is known to be brought into synchronization with a pneumatic clamping lever which is pressed pneumatically onto the strand, i.e. synchronized.
  • the cutting torch is used to carry out the separation.
  • the separating device drives with 3 or 4 impellers on axles or shafts protruding from the machine, driven by a travel drive in the machine housing consisting of an electric motor with gear and brake.
  • the separating device can also be driven in the direction of the strand without being clamped on.
  • the impellers roll on conventional rails, which are mounted on water-permeable hollow profile carriers in hot operating environments.
  • the hollow section girders are also used directly as rails, because of the small cross-sectional size, a statically supplementary second girder is assigned.
  • hoses and cables are predominantly suspended high above the separating device or are guided in special hose and cable trolleys or in caterpillars on special rails or troughs.
  • a type of separating device which is equipped with cooled or non-cooled pipes as raceways, which are enclosed by annular sleeves and which slidably carry the separating device with all other necessary active parts.
  • strand cutting machines 1 are customary, which in portal design consist of heavy carrier profiles or welded box profiles or pipe profiles, and which are then mostly also partially flowed through by cooling water.
  • Correspondingly heavy running and guide wheels 2 with rollers or ball bearings run on running rail supports 3 through which cooling water flows or on corresponding running rails 4 which are mounted on such running rail supports 3.
  • the flame cutting machines 1 are also equipped with all drives and devices including electronic position transmitter for the cutting torch 10, the connection 11 and the method, but not with shut-off and setting devices for the gases of the cutting torch 10, which, together with the pressure reducers, are fixed in place as a gas control station 12 or are arranged on the portal supports.
  • the invention described below is based on the object of finding a physically lighter, less expensive to manufacture, easier to maintain (for example due to better accessibility), easier to use and resource-saving flame cutting system for a modern continuous casting machine.
  • the invention of the separating device of a continuous casting installation described below was possible in that the water cooling of the separating device and the track was to be effected using the simplest, ie most economical, carrier forms.
  • a simple, smooth, perhaps web-like slide rail can be used, for. B. made of stainless steel Place the upper edge under the cooling water level, which corresponds to sliders that also have a particularly favorable coefficient of friction with water as a lubricant.
  • a cleaning effect of the flowing cooling water results in additional advantages if one can prevent the corrosion of corresponding components.
  • the strand cutting area according to the invention is described below:
  • Two gantry girders 6 made of U or H profiles open at the top above the strands 5 are supported by eight supports 13 made of U profiles. These supports 13 are supplemented by rungs 14 to conductors and serve as guide channels for rising / falling supply lines 7.
  • supports 13 are connected to pipes as railings 15.
  • the water-filled portal supports 6 carrying supply lines 7 are covered with walking plates 16 (gratings) and are provided with partition plates 17 which determine the water flow on the inside.
  • the running rail supports 3 are fastened with a U-profile which is open at the top.
  • the water flow in the portal girders 6 is connected to that in these guide rails 3 so that, wherever the cooling water comes from, a cooling water circulation with a certain water level is created by inlet pipes or bores.
  • supply lines 7 are arranged in a protected manner, and in the guide rail supports 3 also the caterpillars 9 for the movement of the flame cutting machines 1.
  • guide rail supports 3 or the portal supports 6 carry the stationary travel drives 18.
  • the Deflection rollers 19 attached, with which the flame cutting machine 1 can be moved on the running and guide rails 4 by means of a pull rope 26 (attached to the flame cutting machine 1) as required or after the end of the cut.
  • the cooling water inflow for the portal carrier 6 and the running rail carrier 3 either comes from the reflux of the burner cooling water, the machine cooling water, from a cooling water line provided for this purpose or from any combination thereof.
  • the flame cutting machine 1 itself in Figures 2 and 3 consists of a base plate 20 which is extended outwards over the running rail support 3 for fastening the skids or rollers 21 in at least three places and to which the movable ends of the caterpillars 9 are also attached.
  • the corrosion-insensitive skids / rollers 21 run, two of them at a distance, in a narrow running and guide rail 4 in the running rail support 3 under the travel drive 18, and at least one roller 21 on the other side on a wide running rail 4 in order to avoid jamming.
  • the cooling water in the running rail supports 3 or on the running rails 4 also serves as lubrication for sliding runners or rollers 21.
  • a novel heat protection plate 22 with the best possible water flow at the lowest manufacturing costs and the highest strength is attached at least five points by welding or screwing in order to stiffen the light base plate. More about this heat protection plate 22 and its execution follows later.
  • Angled webs 23 are inserted in the running rail supports 3, on which the troughs 24 for the caterpillars 9 next to the running rails 4 rest. Aligned one behind the other, for example, above the running and guide rail 4, two retaining brackets 25 for fastening the pull cable 26 are screwed onto the extensions of the base plate 20.
  • a bearing plate 27 for receiving the rotary bearing for the clamping 11, which consists of two clamping levers 28, a compressed air cylinder 29 actuating them and the necessary supply lines 7.
  • the cutting drive 30 with the burner shaft 32 passing through the bearing plate 27 and carrying the burner holder 31 also sits more or less centrally on this end plate 27.
  • shut-off and fine control supply device 34 on the base plate 20, to which mainly the operating resources for the cutting torch 10 such as cutting oxygen, heating oxygen and fuel gas flow, which are already in the fixed main shut-off and pressure reducing device 35 on the gantry carrier 6 were brought to the correct working pressures.
  • Shutting off the equipment after each cut near the torch saves significant gas losses.
  • the most precise nozzle-specific flame setting can be carried out quickly and precisely on the machine.
  • a self-regulating arrangement of orifices, which partially compensates for nozzle wear or blockage, is only possible near the burner, as is the branching of heating oxygen and fuel gas for an ignition flame that is constantly burning for safety reasons, which is only sensible and economical here.
  • Back-and-forth pipe coils are known, with sheets placed on or hung underneath to cover the gaps, only good for the case b. Furthermore, square tubes welded to each other with welded end covers and pipe bends welded in this, only good for the case a. Double sheet heat protection plates, edge welded with welded bolts to reduce buckling, not particularly suitable for cases a, b or c.
  • Cooling tubes 37 are pressed together twice at their ends: once to produce a sufficiently large and flat drilling surface 39 and at the very end then again to close the tube end, if necessary after inserting a strip of sealing material. Thereafter, a threaded hole is alternately machined in the drilling surfaces 39.
  • two cooling tubes 37 for cooling water are connected continuously. With the next passage nipple 40, the other side of one of these cooling pipes 37 is screwed to another, the other side of which is connected to the next.
  • the strength of the entire heat protection plate is determined by brackets 41 over the ends of two adjacent cooling tubes which are not screwed in each case 22 improved. More or less long welds between the cooling tubes 37 serve the same purpose. But it is also possible to clamp the heat protection plate 22 screwed together in longitudinal U-profiles at both ends or similar.
  • FIG. 6a and 6b Another example of a light continuous cutting machine 1 in a continuous casting plant according to the claims according to the invention is shown in Figures 6a and 6b and is hereby described as follows: Above the strand 5, the flame cutting machine 1 is arranged on only one known rail carrier 3, as described above, which is cooled by water and carries supply lines 7 and the line caterpillar 9.
  • the machine hood 33 is more stable here and the running rail support 3 is made comprehensive. It carries 3 or 4 sliding shoes / rollers 21 which run on the two upward-facing flanges of the running rail support 3 or on 2 light profiles (not shown) in the running rail support 3 in or above the cooling water.
  • the machine hood 33 is provided with side flanges for attaching a machine trough 43 by pushing in or screwing on.
  • the two brackets 25 for the traction cable 26 of the traversing drive 18 are attached.
  • the bearings for the clamping levers 28 of the clamping 11 and the burner shaft are on the light base plate 20 or on the front end plate 27, as is known 32 or the cutting drive 30 attached.
  • An open cooling water flow could be in the machine trough 43, but the supporting, supplementary and protective arrangement of a heat protection plate 22 underneath is provided as better.
  • portal supports 6 with partition plates 17, walking plates 16, railings 15, main shut-off and fine control supply device 35 are also implemented in the flame cutting machine as already described.
  • An axis of rotation of the cutting torch 10 lying perpendicularly above the strand is also advantageous, especially if the two clamping levers are also moved about this same axis of rotation when connecting. With that Clamping movement and cutting movement are the same and a simple, most precise edge detection for cutting is possible.
